💅 onenand_release_device — from the Kernel API Manual, bestie

Okay so this is onenand_release_device(9), straight out of the kernel API manual, and I'm gonna walk you through it like we're on FaceTime at 2am. It's short. It's iconic. Let's go. ✨

✨ NAME ✨

onenand_release_device — [GENERIC] release chip</p> 🫶

---

🌸 SYNOPSIS 🌸

void onenand_release_device (struct mtd_info *mtd );

---

🎀 ARGUMENTS 🎀

• mtd — the MTD device structure. That's it. That's the whole argument. She's simple, she's elegant. 👑

---

🦋 DESCRIPTION 🦋

Okay so what does she actually do? Three things, and honestly? She ate. 🔥

• Deselect — unselects the chip, like leaving the group chat.
• Release the chip lock — drops the lock so other threads can finally get in. no more gatekeeping 💅
• Wake up anyone waiting on the device — yes bestie, she's the one who wakes the whole waiting room up. main character energy fr fr.

So basically: deselect, unlock, and wake everybody up. Clean, courteous, done. 😭✨
